<p>The GNU Objective-C runtime used to provide a different API, which we
call the &ldquo;traditional&rdquo; GNU Objective-C runtime API.  Functions
belonging to this API are easy to recognize because they use a
different naming convention, such as <code>class_get_super_class()</code>
(traditional API) instead of <code>class_getSuperclass()</code> (modern
API).  Software using this API includes the file
<samp>objc/objc-api.h</samp> where it is declared.
</p>
<p>Starting with GCC 4.7.0, the traditional GNU runtime API is no longer
available.
